Embodiment Construction
[0011] The present invention will be further described below in conjunction with accompanying drawings and examples.
[0012] The protocol is divided into three stages, the first stage completes the exchange of local energy information ( figure 1 , figure 2 ). Each node diffuses its own residual energy information group to its adjacent area with period T. Each node shall hold a sequence number seq. Each remaining energy information packet carries the following information: source node id value, seq value, remaining energy value of the node, TTL value. The initial value of Seq is 0, and the seq value is increased by 1 every time this type of group is diffused. The TTL value indicates the range (hop count) over which the packet can be flooded. In this way, an energy information packet can be uniquely identified through the seq value and the id value, avoiding repeated forwarding by intermediate nodes. Moreover, seq can identify the freshness of the energy information pack...
